Improvement in lift-pumps



UNITED STATES EMORY BARNES, OF MOUNT PLEASANT, MICHIGAN.

IMPROVEMENT IN LIFT-PUMPS.

Specification forming part of Letters Patent No. 195,253, dated September 18, 1877; application filed August 18, 1877. I i

To all whom it may concern:

Be it known that I, EMORY BARNES, of Mount Pleasant, in the county of Isabella and State of Michigan, have invented a new and Improved Pump, of which the following is a specification This invention has relation to means for raising water; and the nature of my invention consists in combining, with a submerged cylinder, a piston which is depressed by a helical spring and raised by means of a treadle and a chain, which is attached to the piston-rod and passed over a pulley attached to the discharge-pipe, as will be fully explained hereinafter.

1n the annexed drawing I have represented my improved pump in section, arranged in a well.

The letter A designates the curbing of a well, at the bottom of which, and submerged in the water, is the pump-cylinder B. This cylinder may be of any suitable length and diameter, and it should be secured down in any suitable manner. The base of the cylinderB is perforated so that water will flow freely into it when apiston, O, israised. This piston is provided with valves to a, which open upward and which allow water to flow when it is depressed. D designates the piston-rod, which has a helical spring, E, compressed between the piston and head of the cylinder for the purpose of giving the downstrokes to the piston. The upper end of the piston-rod has a chain, G, secured to-it, which extends above the top of the well andis passed over a pulley, H, and attached to a treadle, J. By depressing the treadle J the piston D will force water up through the discharge-pipe K. At the foot of this pipe is a check-valve, d, which allows piston D to force water up the pipe, but prevents it from returning. The pulley H has its bearing in a journal-box, which is supported by a bracket, L, fixed to the stand-pipe K.

Having thus described my invention, What 1 claim as new, and desire to secure by Letters Patent, is

In combination with the submerged pumpc'yllnder having a perforated bottom, and with a piston, 0, having valves a, the spring E, rod

D, chain G, pulley H, and treadle J, arranged substantially as described.
